Next to the severe storms battering parts of America this weekend. We kick it off with the storms in the northeast. This is the ominous sky over Brooklyn overnight and it came with drenching rains that triggered flash floods and closed roads like here in central Pennsylvania. Meanwhile in Texas, fear winds knocked rail cars off the tracks and twisted silos into a mangled mess. Texas is in the cross hairs tonight. Meteorologist Stephanie Roberts is here with the forecast. Tell us about the severe threat tonight. I think we're already going to see the flooding rains become more of a problem, a new flash flood watch has been issued that's going to include Minneapolis. We've seen this severe thunderstorm watch include Denver, that severe risk moves to the east and is going to include Chicago on Sunday. Dan, the difference tonight is we don't think things are going to wind the down overnight. People need to keep their guard up through the overnight hours. We're heading into a nervous night. Let's talk about father's day. Aloft lot of people keyed into that. What are we looking for? Great on the coast for golf, fishing, dad will be in great shape. We're still going to have that severe storm risk in the middle of the country. The rain chance stretches from Minneapolis to Dallas and still cool and damp in the northwest. Meteorologist Stephanie Roberts, thank you.
